OAKLAND -- The Golden State Warriors' move to San Francisco won't just cost Oakland and Alameda County residents an NBA basketball team, it might cost them upward of $60 million.

Representatives of the board that runs the Oakland-Alameda County Coliseum complex said attorneys for the Warriors have informed them that the team will stop paying down the debt on the Oracle Arena after it decamps for San Francisco, even though it appears that a clause in their lease requires them to keep making payments.

Oakland School Board member Chris Dobbins, who also sits on the Coliseum board, said he hoped public pressure would force the Warriors to reconsider and avoid a legal fight. "If the Warriors are going to double their franchise value and make all this money by moving to San Francisco, to screw the taxpayers of Oakland and Alameda County is ludicrous," he said.

Oakland and Alameda County jointly own the arena and issued $140 million in bonds nearly 20 years ago for upgrades to keep the Warriors in town.

The Warriors have been paying up to $7.4 million a year to cover debt service payments, but under the team's lease those payments do not end just because the team leaves town.

The lease states that if the Warriors leave before June 30, 2027, the team has to pay any debt service that is not covered by the arena's net operating revenue as long as the arena remains open for business.

The Warriors would not say why they considered themselves unbound by the lease clause. Team spokesman Raymond Ridder said in an email that "We will continue to honor all terms of our lease at the Oracle Arena."

The bond debt currently sits at $85.9 million and is expected to drop to $62 million when the Warriors are scheduled to depart at the end of the 2017-18 season.

Deena McClain, the Coliseum board's interim director, said she could not forecast how much operating revenue would fall without the Warriors.

The debt issue will likely be part of upcoming talks for a one-year extension to the Warriors' lease, which is scheduled to expire in at the end of the 2016-17 season.
